My Evo's Dyno - input needed please!
I agree. You asked for help, what if everyone said...I think I know the issue, PM me and I'll tell you.... It would greatly defeat the purpose of forums. You can explain the issue and be honest and not trash talk someone, or thier work. If it's true, it's true. Just put it nicely and name no names. No one is perfect.
Also, how different do both dyno's read? I mean the GST dyno could read higher and inflate your numbers, which means something still may be wrong. I sure hope that's not the case and am not trying to instigate anything, just throwing out another possibility. If it's not the case, then congrats on getting everything squared away and making some solid numbers!
The OP's Evo spun the rollers with the original tune and boost control to 276whp/275wtq (the dotted lines on the GST power chart). After we put our boost assembly on and retuned the car it made 295whp/271wtq. Which is pretty darn strong for the mods this car has. The normal would be around 28Xwhp.
The car when it came in had the factory boost assembly with the solenoid side pill out. This does increase the boost about 2 psi or so but still tapers off up top. (Seen in the boost/afr chart earlier in this thread, the dotted lines are before). Our Boost assembly keeps the stock solenoid pill but upgrades the turbo side pill to allow a totally custom boost curve. It also allows the car to hold more boost up top, as you can see in the solid boost curve line in the boost/afr chart posted.
